1646355-34-1 Usage
General Description
Linagliptin Impurity H is a chemical impurity associated with the diabetes medication linagliptin. It is characterized by the presence of a specific molecular structure that differs from the pure form of linagliptin. This impurity could potentially affect the safety and efficacy of the medication. Therefore, it is important for pharmaceutical companies to monitor and control the levels of Linagliptin Impurity H in linagliptin formulations to ensure the quality and purity of the medication for patients. Analytical methods such as HPLC and mass spectrometry are often used to detect and quantify this impurity in pharmaceutical samples.
Check Digit Verification of cas no
The CAS Registry Mumber 1646355-34-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,6,3,5 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1646355-34:
(9*1)+(8*6)+(7*4)+(6*6)+(5*3)+(4*5)+(3*5)+(2*3)+(1*4)=181
181 % 10 = 1
So 1646355-34-1 is a valid CAS Registry Number.
